MAMBOURG GLASS TANK Filed March 5, 1927 gm iov m m n H Patented Mar. 18, 1930 UNITED STATES PATENT OFFICE LEOPOLD MAMBOURG, OF LANCASTER, OHIO, ASSIGNOR TO LIBIBEY OWENS GLASS COM- CPANY, OF TOLEDO, OHIO, .A CORPORATION OF OHIO GLASS TANK Application area March a, .1927. serial no. 172,224.

The present invention relates to glass apparatus. I An important object of the invention is to provide in'glass apparatus, a tank furnace ineluding a working receptacle and adjustable jack-arches or walls adapted to be partially dipped into the glass.

Another object of the invention is to pro vide in glass apparatus,,a tank furnace ineluding a jack-arch adapted to have its end dipped into the molten glass contained in said furnace to retard movement of the upper stratum of said glass.

Still another object of the invention is to l provide in glass apparatus, a tank furnace including a jack-arch having its lower end disposed beneath the level of the molten glass passing thereunder, said jack-arch having means adapted to convey glass toward the posed of as desired. I

A further and important object of the invention is to provide in glass apparatus, a tank furnace including a cooling chamber,

said cooling chamber having an adjustable v cap and a jack-arch having its lower end disposed beneath the surface of the molten glass passing thereunder so that sub-surface glass only will pass under said-jack-arch.

A still further object of the invention is to rovide in glass apparatus, a tank furnace including a cooling chamber, said cooling chamber havingan adjustable cap and a ackarch having its lowerend disposed beneath the surface of the molten glass passing thereunder so that sub-surface glass only will pass under said jack-arch, the upper stratum of glass being caused by said j ack-arch to move toward the sides of the cooling chamber where it may be poured into receptacles containing Water, thus forming cullet from said skimmed lass. b A further object of the invention is to provide in sheet glass apparatus, a tank furnace including a cooling chamber having an insulated bottom and an adjustable cap, said cooling chamber having connected thereto a draw-pot and an adjustable jack-arch arranged somewhere between the-melting end of the tank furnace and the draw-pot and sides of said furnace where it may be disadapted to have its lower end arranged below the surface of the molten glass in a manner that the top stratum. of glass may be dammed off, while the sub-surface glass will be free to flow toward said draw-pot from which point it may be drawn into sheet form.

Other objects andadvantages of the invention will become more apparent during'the .course' of the following description when taken in connection with the accompanying drawings.

In the drawings wherein like numerals are employedto designate like parts throughout the same- Fig. 1 is a vertical longitudinal section through my improved form of furnace, and

Fig; 2 is a vertical transverse section thereof taken on line 22 and looking in the direction of the arrows. I

Although the drawings illustrate a sheet glass machine associated with the tank furnace, it is to be understood that any form of glass working machine can be associated with the working receptacle or receptacles connected to said furnace.

niay be produced by melting suitable ingredients in any desired manner. The numeral 7 designates a cooling chamber in its entirety which is preferably provided with an insulated bottom 8 and an adjustable cap 9. The cap 9 may comprise a plurality of refractory blocks 10 supported by means illustrated diagrammatically, and numbered 11. It is to be understood that the cables 11 illustrated are purely diagrammatic, and that any suitable supporting means may be used to adjustably mount the cap in position.

A working receptacle or draw-pot 12 is connected to the cooling chamber 7 and is adapted to receive molten glass passing from the tank furnace 5 and through the cooling chamber 7. As illustrated, a sheet of glass 13 may be continuously drawn from the mass of molten glass 14 contained in said draw-pot, the sheet being deflected over a suitable member 14; and passing over a flattening and drawing table 15. Lip-tiles l6 and shields ill ' t e molten glass so that sub-surface glass only 17 may be provided to protect the sheet 13 during its vertical rum-while suitable edge engaging means 18 may be used to prevent narrowing of thesheet at its base.

Jack-arches 19 and 20 respectively are provided, and may be adjustable vertically, as desired, although for the sake of sin'iplicity, the adjusting means are not illustrated. Although the jack-arches are illustrated as being located in the cooling chamber 7, one or more of such arches may be located anywhere along the tank furnace from the melting end to the t The lower ends 21 of the jack-arches are apted to be dipped below the surface 22 of will be free to pass toward the working end. To facilitate removal of the upper stratum of glass, which is dammed oil' by the partially submerged ack-arches, a suitable trough means 23 may be carried by said jack-arches whereby themolten glass may flow into the trough means which are shaped as illustrated in Fig. 2 to facilitate flowing of said glass towards the sides of the furnace. As showm'the troughs 2-3- have bottoms inclined from the highest point 24, which is preferably central- ,l{ thereof, toward both ends. The ends of e troughs may extend past the side walls 25 of the cooling chamber where suitable rcceptacles 26 may be placed and filled with water 27. The molten glass will be chilled by contact with the water, forming what is known in the art as cullet, and which is numbered28. The cullet 28 may be used again, in the batch from which the molten glass is produced.

a By skimming off and disposing of the upper stratum of glass, and by causing the subsurface movement of the glass toward the draw 0t 12, a higher quality of glass will be furnis ed to the draw-pot, and subsequently to the sheet 13 than in those cases where the glass is melted and permitted to flow freely toward the working end of the furnace.

Another advantage resides in the fact that the jack-arches, or a single jack-arch if desired, will effectively separate the heated gases above the melting chamber or melting end of' the furnace from the cooling chamber. and will also in the construction illustrated separate the gases above the cooling chamber from those in the draw-pot. By separating the gases above the molten glass as pointed out, it is possible to create and maintain desired working conditions at these several points, so that the gases in the melting end will not affect the drawing operation at the (lrawpot and vice-versa.

It is to be understood that the form of the invention herewith shown and described is to be taken as the preferred embodiment of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit lllll lllll lllll lllll llll Hill

of the invention or the scope of the subjoincd claims.
